The third objective at zero + 2 hours.
The fourth objective at zero + 4 hours 30 minutes.
9. The attack will be carried out as follows:
The 2nd and 3rd Battalions Coldstream will attack and capture the first, second, and third objectives. The 2nd Battalion Grenadier Guards will move in rear of the two Coldstream battalions. When the latter advance to the assault of the second objective this battalion will occupy the first objective until the 1st Battalion Irish Guards has passed through them. They will then follow and support the Irish Guards in their attack on the fourth objective. The rôle of this Battalion is to form a defensive flank, if necessary, and to support the attack of the Irish Guards. The Irish Guards will attack the fourth objective.
10. The Battalion will advance in the same formation as it forms up (two lines at 100 yards’ distance of two
companies each in lines of platoons at 40 yards’ interval). If it comes under rifle or machine-gun fire it will deploy into extended order.
11. When the Coldstream have captured the first objective the Battalion will halt until zero + 1 hour, probably in the old British front line.
12. Battalion Headquarters will move about the centre of the two rear companies. A dressing-station will probably be established in the old British front line.
13. As soon as the final objectives have been captured by the infantry, the cavalry will advance and seize the high ground ahead.
14. The first line transport will be packed up and ready to move forward at one hour’s notice after zero + 4 hours.
